stimulus test bench

jyoti kandpal

hello sir, sir when I test my circuit in test bench how I can decide the size of two cascaded inverter size that is best of my circuit. Is there any method to decide the size of inverters? please help me. I am attaching the image of test bench.

    This is a very open ended question and difficult to provide a conclusive answer as the size of the inverters driving your circuit under test is a function of your circuit's operation. Usually, a test bench is designed to examine the performance of a component used in a larger system. Hence, the circuit driving the device under test models the drivers of the preceding stage. If you know what is driving your circuit, examine its output drivers and size your input inverters accordingly. Otherwise, choose the sizes based on sizes that optimize the performance of your circuit under test and specify the size of inverters required as a requirement to assure proper operation of your circuit under test.

    I am unable to provide a specific recommendation as I have no idea what your circuit under test is designed to do nor its operational parameters.
